Welcome to CreateRDS,
This facility is designed to allow you to create reference sets for DichroMatch or DichroWeb. For dichromatch you are only required to upload data about your spectra, this may include concentration, pathlength, protein weight and current units (if you wish to convert data to delta epsilon - which we strongly suggest).
To create a reference set for DichroWeb you will also need to provide a PDB accession code. We will fetch the structure from the PDB and analyse the secondary structure content using DSSP. The output will comprise two files: the spectra file (in CDPro format) and secondary structure definitions following the rules described by Sreerama, Venyaminov and Woody.
